UNITED STATES PATENT OFFICE.

RICHARD A. STRATTON, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HIMSELF AND OHAS. H. MILLER, OF SAME PLACE.

IMPROVEMENT IN ADJUSTABLE HANGERS.

Specification forming part of Letters Patent N0. 38,539, dated May 12, 1863.

To a/ZZ whom it may concern.-

Be it known that I, RICHARD A. STRA'ITON, ot' Philadelphia, Pennsylvania, have invented an Improvement in Adjustable Hangers; yand I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists of a' hanger constructed inA the manner fully described hereinafter, with the view of readily adjusting the b x 0r bearing both vertically and laterally, and securing the same after adjustment.

In order to enable others skilled in the art to make and use my invention, I-will now proceed to describeits construction and operation.

On reference to the accompanying drawings, which form a part of this specification, Figure l is a vertical section of my improved hanger Fig, ,2, a transverse vertical section; and Fig. 3 a sectional plan on the line l 2, Fig. 1.

Similar letters refer to similar parts throughout the several views.

A represents the upper plate of the hanger, which is secured by means of bolts or screws passing through oblong slots a to the under side of the iioor or floor-beams of the room in which it is desired to hang a line of shafting. The inverted arch-piece b forms a part of the hanger, and, viewed transversely, is of the semi tubular form represented in Fig. 2. From this arched portion b depends the stem d of the hanger, which may be of tubular or cylindrical form or of the semi-tubular form seen in the sectional plan, Fig. 3, the lower end of this stem being provided with a horizontal projection, e, through which passes the screw B, the latter being provided above the said projection with a suitable tightening-nut, f. The bearing or box of the hanger is composed of the upper portion, D, and lower portion, D', adapted to each other in the manner illustrated in Fig. l, so that the upper portion cannot move laterally independently of the lower portion. This lower portionD of the box or bearing is provided with a ange or plate, which is semi-cylindrical, as seen in Fig. 3, and so adapted to the semi-tubular stem d of the hanger as to turn on the same. Two bolts, h h, pass through the stem of the hanger and through the plate t' of the lower portion, D',

of the bearing, the holes in the plate for the reception of the bolts being oblong horizontally and those in the hanger oblong vertically, so that the plate with the box or bearing can be readily adjusted by turning it laterally on the stem, or sliding it up and down vertically. The set screw B in the projection e serves to adj ust and support the box or bearing, and a setscrew, G, in the inverted arched portion of the hanger bears on the top of the box and serves to steady the same after adjustment. After securing the hanger to the floor in a position approximating to that which it has subsequently to occupy, the box is elevated or lowered by means of the screws B and G (the nuts of the bolts h h bein g loose) until the center of the box coincides as regards altitude with the center line of tl e shafting. The box is then adjusted so that its center sh allbe in the same horizontal lines as the center of the shafting by simply turning the said box on the stem to the extent desired, and, it' necessary, moving the entire hanger on the beam, a movement permitted by the oblong openings c in the plate A. After proper adjustment the box is firmly secured by tightening the nuts of the bolts h hand the set-screws B. It should be understood that in securing the hanger to the beam in the rst instance the stem d must be perpendicular.

H is a cup or reservoir, secured to the stem d in such a position as to receive the superuous lubricating matter which passes from the box.

I claim as my invention and desire to secure by Letters Patent- The hanger, .with its cylindrical or semitubular stem d and its set-screws B and G, in combination with the two portions D and Dl of the box, the latter portion having a plate, i, adapted to and rendered adjustable on the stem of the hanger, and the whole being constructed and arranged'substantially as and for the purpose herein set forth.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.

RICHARD A. STRATTON.
